The Oriskany Battlefield is described as haunted due to reports of ghostly phenomena, including spectral figures, the phantom sounds of drums and gunfire, and the distinct smell of gunpowder. Visitors have claimed to feel a physical impact from an unseen presence and believe these sensory experiences are echoes of the brutal 1777 Battle of Oriskany, where numerous soldiers from both sides died. The ravine area, where the battle's ambush took place, is often cited as the most active spot for these occurrences. Witnesses have described seeing a white figure of a human, often referred to as a ghost, running into the weeds after making physical contact with someone. Visitors have heard the distinct sounds of drums, shouting, and the crackle of muskets and gunfire. Some people report smelling the sharp, acrid scent of gunpowder, even though no actual gunfire is occurring. One visitor described being physically "crashed into" by a spectral presence.
